mapi.session (emailing via CDO)

[ItsMe]

...
I noticed the code from blue-claw didn't include the statements:
Set iConf = CreateObject("CDO.Configuration")


iConf.Load -1 'CDO Source Defaults
Set Flds = iConf.Fields
...

That is because the code example in Blue Claw does not depend on a reference. Instead, it depends on the schemas defined. But I am not sure how these types of schemas work, exactly.

Just to add another reference to this thread, here is an example of using a return receipt. The actual return receipt code is commented out. So it is easy to spot.

I know of some ISP's that will suspend service if multiple attempts to send emails to more than 50 addresses, so in such cases 1,000 wouldn't even get out the first time.

I don't currently have a need for incoming, but I'll save the VB6 code for future reference.

I have some additional error condition checking to do in my app that uses the outgoing email, but the send email code works perfectly.

Ajax,
One needs to buy a license to obtain and use the DLL for the codes obj library reference. Otherwise, I'd tailor the posted VB6 code to run as a VBA general module.
